The Suffolk County District Attorney's Office in Boston said in a statement that the deaths of a 67-year-old woman from Tiverton, R.I., and a 23-year-old man from Littleton, N.H. are not considered suspicious.

Around 6:30 a.m. Friday, the Norwegian Dawn cruise ship returned to Cruiseport Boston’s Black Falcon Terminal after a week-long venture to Bermuda with two dead bodies aboard. Detectives with three different divisions of the Massachusetts State Police and FBI agents began looking into the situation.

Following an investigation, they determined that the two people died separately and without a criminal element at play.

Authorities said that in the absence of criminal charges, no further information, including the names of the deceased, will be released.
